China News Service, April 17. Huang Weifen, chief designer of the astronaut system of China's manned space project and researcher of the China Astronaut Research and Training Center, said today that according to the task arrangement during the construction phase of the space station, the astronauts who performed two manned flight missions will be onboard. Group has been selected.

At present, the physical and mental conditions of the flight crews of Shenzhou 14 and Shenzhou 15 are very good, and they are actively carrying out relevant training and mission preparations.

  On the afternoon of the 17th, the State Council Information Office held a press conference on the progress of the construction of China's space station.

At the meeting, a reporter asked: After the successful return of the Shenzhou 13 astronaut crew, people from all walks of life are looking forward to the follow-up manned mission.

There are also two batches of six astronauts to perform flight missions this year.

Excuse me, what needs to be done by the crew of Shenzhou 14 and Shenzhou 15 in orbit?

How is the current preparation work going?

  While making the above response, Huang Weifen said that the two crews of Shenzhou 14 and Shenzhou 15 will fly in orbit for 6 months, and will realize the rotation of the crew on-orbit for the first time, realizing uninterrupted presence of people.

Two crews of six astronauts will stay in orbit for 5-10 days, and the astronaut system will face more severe challenges.

  Huang Weifen said that the 14th crew will cooperate with the ground to complete the assembly and construction of the space station, from the single-cabin assembly flight to the three-cabin assembly flight state gradually. Separate evacuation and 2 transposition missions; they will be stationed in Wentian experimental cabin and Mengtian experimental cabin for the first time to establish a manned environment; cooperate with the ground to carry out two-cabin assembly, three-cabin assembly, and large and small robotic arms tests. For the first time, the airlock cabin will be used to carry out exit activities; the unlocking and installation of 14 cabinets in the Wentian experimental cabin and the Mengtian experimental cabin will be completed.

The flight crew of Shenzhou No. 15 will also plan to carry out several out-of-vehicle activities, to assemble, test and debug the load equipment in the cabin, control the mechanical arm to implement the installation of the load outside the cabin, and operate the largest configuration combination of three cabins and three ships. management and maintenance.

The two flight crews will also carry out popular science education and other public welfare activities, and carry out dozens of on-orbit scientific research experiments and engineering technology tests, as well as flight mission data collection and photography; Orbit training and drills, as well as a large number of space station platform inspections and tests, equipment maintenance and care, station services and material management.

  Huang Weifen pointed out that in view of the characteristics of the flight tasks in the construction stage, the astronaut system has designed and implemented more than 200 training items in eight categories based on the principle of "being strict with difficulties, starting from actual combat, and integrating trial training", so that astronauts can improve their mind and body. , psychology, knowledge reserves, operational skills and other aspects have the ability to perform flight tasks.

On the basis of comprehensive system training, we focused on the following aspects of intensive training:

  The first is to carry out intensive training for the first-time stationed state settings of the Wentian capsule and the Mengtian capsule, as well as the operation management, equipment operation, maintenance and repair, material management, and station management of various configuration assemblies.

  Second, for tasks such as the verification of the robotic arm and the activities of exiting the airlock, the training of manipulator operations, the procedures for exiting the cabin, collaborative training, simulated weightless water tank training, and low-pressure environment training have been completed.

  The third is to strengthen the training of emergency fault handling capabilities and the training of remote operation rendezvous and manual control rendezvous and docking of experimental cabins.

  The fourth is to strengthen physical and strength training, psychological adjustment training, and on-orbit health, life and work residency guarantee skills training.

  The fifth is to complete dozens of space experiments (trials) and platform operation training.

  Sixth, it has participated in nearly 100 engineering development and testing activities such as man-ship joint test, man-station joint test, and ergonomic evaluation test, and deeply participated in the preparation of flight manuals and plans.

While giving full play to the role of astronauts, continuously improve their comprehensive combat capabilities.

  "In addition, individualized training and individualized health protection work have been strengthened, and two crews have been arranged to communicate with the flight crews of Shenzhou 12 and Shenzhou 13 many times. On the basis of Shenzhou 13 missions, further improvement and Improve the guarantee measures for astronauts to stay in orbit for a long time to ensure that astronauts live a healthy life in orbit, work efficiently, and successfully complete their tasks." Huang Weifen said.
